Original Redmine Issue: 6017
Affected QGIS version: master
Redmine category:rasters

I've calculated an enviromental index, and because of the input data many pixes of the final product contain many values. When I load the image to qgis, and tabing to histogram page, the resulting histogram is unsualble due the large amount of chaff. Picture attached. !broken-hist.JPG!
